FEED- WATER PURI'FIER.

SPEGIEIGATION forming part of Letters Patent No. 532,082, dated January 8, 1895;

Application filed time 20, 1893.

Serial No. 478,281. (No model.)

To all whom it may cortcern:

Be it known that I, JOSEPH MOHR, a citizen of the United States, residing at Chicago, in

the county of Cook and State of Illinois, have construction and the combinations of parts hereinafter fully described and specifically claimed.

In the accompanying drawings illustrating my invention-Figure 1 is a central vertical section. Fig. 2 is a cross section on the line 2-2 of Fig. 1.

Referring now to said drawings, A in dicates the cylinder of my improved feed water purifier provided at one end with a feed pipe 1 and at its other end with an outlet pipe 2 leading to thebottom ofthe boiler. The said cylinder A is divided at certain points between its ends by partitions 3,which inthe instance illustrated are two in number, dividing the cylinder thus into three compartments. The said partitions 3 rise only partially to the top of the cylinder so that the water can pass over the upper edges of said partitions to the out-- let pipe 2. The compartments 4: made by said partitions 3 are provided with what 1 term bafiie plates 5 which consist of perforated plates placed at an incline and suitably secured in the compartments 4 and extending from the lower end of one partition upwardly to the upper edge of the succeeding partition, the upper ends of the baffle plates being secured to the partition 3 of any particular compartment that is farthest from the outlet pipe 2. The 'partitions3 are arranged so that they decrease in height as they approach the outlet pipe 2, which outlet pipe 2 connects with the cylinder Aatapoint below the upper edge of the adjacent partition 3, as shown in Fig. 1. The feed pipe 1 preferably passes through the bottom of the cylinder and through the last of the baffle plates 5 to a point about on a level with the upper edge of the last partition 3.

A pipe 6 communicating with a source supplying steam is provided with the branches 7, and these branches communicate with the cylinder .A, one over each compartment 4, while at the bottom of the cylinder are three branches 8 communicating with each compartmentand with a blow-off pipe 9.

j The branch communicating pipes 8 and the blow-off pipe 9 are each provided with controlling valves 9% by means of which the water is retained at different levels in the several compartments 4 of the cylinder.

The-operation of my invention is as follows:

Water being admitted to the cylinder A through the pipe 1 fills up these succeeding compartments thereof and passes out through the outlet pipe 2 to the boiler. In passing through thecylinder A, however, the sediment and impurities carried by the water are precipitated in the usual manner and falling upon the battle plates of the compartment pass through the perforations thereof beneath the same, or fall down along their inclined faces as will be obvious. By arranging the different partitions of different size, decreasing from the first toward the outlet pipe, it will be seen that the upper strata of water, or that which parts with its impurities first, can pass along toward the outlet pipe first, while the rest of the water or the impure part will be arrested by the partitions while the impurities are being precipitated. It will be noted that by reason of the baffle plates 5 any impurities that settle in the compartments t will pass through and below the battle plates so that they will be undisturbed and cannot mix with the pure water, since these baffle plates prevent the currents in. the cylinder from reaching the precipitated impurities, so that they remain in the bottom of the cylinder where they fall. By means of 9 5 fierI arrange a steam supply pipe 7 and a red blow-01f pipe 8 above and below each of these from the bottom partially to the top of the casing to form a plurality of compartments, and baffie plates 5 located at an incline Within said compartments with their upper ends adjacent to the end of the casing at which the supply pipe l is located, substantially as described.

2. A feed Water purifier comprising a casing A having a supply pipe near one end thereof and an outlet pipe 2 at the other end, a plurality ofupright partitionslocated with"- in such casing and extending from the bottom thereof partially to the top of the same and decreasing in height from the supply pipe toward the outlet pipe, baffleplat'es located within the compartments formed by said partitions, and arranged at an angle with their upper ends adjacent to the end of the "supply pipe, substantially as described.

3. A feed water purifier comprising a casing A divided into a plurality of compartments and provided at its ends with feed and outlet pipes l and 2 and steam supply and blow-oh? pipes communicating with said casing above and below each of said compartments, substantially as described.

4. "A feed water purifier comprising a casing A provided at its ends with feed and outlet. pipes 1 and 2, a plurality of upright partitions 3 extending from the bottom of said casing partially toward the top thereof, a plurality of inclined baffle plates 5 secured within the compartments formed by'said partitions and having their'upper ends'adjacen-t'to the end of t'he'feed pipe and steam supply and blow-off pipes communicating with said casi-ngabove-and below each of said compart- Intestimonywhereof I affix'my sign-aturein presence of two witnesses.
